Description

A banana straw grinder

technical field

The utility model relates to a pulverizer, in particular to a banana straw pulverizer, which belongs to agricultural machinery.

Background technique

Because the plants of bananas are relatively tall, while a large number of bananas are produced every year, a large amount of agricultural waste such as banana stalks is produced. At present, the use of banana straw in my country is mainly used as livestock feed and the extraction of fertilizer and fiber used in farmland, but the agricultural waste used in these three ways accounts for a very small proportion of the annual banana straw production. Most farmers in my country deal with straws by naturally piling up and rotting straws or burning them back to the field. However, banana straws have a high water content, lignin, cellulose, and hemicellulose content, which will cause incomplete straw burning. The long decay period and other problems make the straw take up a lot of space for a long time and affect the efficiency of agricultural production to a certain extent. Although the domestic banana straw crushing machinery has been developed to a certain extent, there are mainly two types of fixed type and traction type. The traction type is pulled by a tractor to directly crush the straw in the field, but because of the characteristics of the banana straw itself, it is easy to cause crushing. It is not thorough, which affects the next cycle of crop planting; the fixed type is to manually move the straw to a specific location, and then use a special machine to crush the straw intensively. Compared with the traction type, the crushing effect is to a certain extent It has been greatly improved, but the rate of returning crushed straw to the field is low. Therefore, a banana straw grinder with small crushing particles, high crushing efficiency and good crushing effect is needed, which can also increase the rate of returning crushed straw to the field.

Contents of the invention

The purpose of the utility model is a banana straw grinder with small crushing particles, high crushing efficiency and good crushing effect, which can increase the recycling rate of straws and increase the rate of returning crushed straws to the field.

In order to achieve the above object, the technical solution of the utility model is to provide a banana straw grinder, including a conveying device, a casing, a roller shaft, a motor, a rotary cutter, a screw conveying device, a zigzag cross crushing blade, a crushing device, The transmission device, the inherent motor Ⅰ under the conveying device, the side of the motor Ⅰ is equipped with a rotary cutter; the sawtooth cross crushing blade is arranged under the roller shaft, and the spiral transmission device is arranged under the sawtooth cross crushing blade. The roller shaft, sawtooth The cross-shaped crushing blades and the screw transmission device are all located in the casing; one side of the motor II is connected with a transmission belt, one end of the transmission belt is connected with a screw transmission device, and the top of the transmission belt is connected with a gear, and one side of the gear is inherently zigzag-shaped cross crushing blades; The crushing device includes two rotating shafts and two sets of crushing blades; the transmission device includes a gear meshing mechanism and a transmission belt.

The rotary cutter includes a rotary shaft, a rotary knife rest, and a rectangular blade. The rotary knife rest is connected with a flat key through the rotary shaft. The rotary knife rest is provided with a rectangular blade. The blades are evenly distributed on the circumference.

The two groups of crushing blades adopt intersecting zigzag crushing blades.

The transmission device adopts a V-belt transmission mode.

Compared with the prior art, the beneficial effects of the utility model are: the advantage of adopting double-sided blades is that when one side is worn out, the direction of the blades can be changed directly, saving the cost and time of changing the blades; The axis of rotation is the same as the feeding direction of the banana straw, and under the action of the inclination of the conveying device, it forms a certain angle with the banana straw, so that the blade surface is approximately perpendicular to the fiber of the straw, which helps to crush the straw better; Small particles, high crushing efficiency, and good crushing effect Banana straw grinder can increase the recycling rate of straw, and increase the rate of crushed straw returning to the field, which helps to solve the current environmental pollution caused by incineration or natural decay problems, so as to promote agricultural development more effectively and better.

detailed description

In order to describe in detail the technical content and structural features of a banana straw grinder of the present utility model, the following will be further described in conjunction with the embodiment and accompanying drawings.

As shown in Figures 1, 2, 3, 4, and 5, a banana straw shredder includes a conveying device 1, a casing 3, a roller shaft 4, a motor, a rotary cutter 6, a screw conveying device 7, and a zigzag cross crushing machine. Blade 11, crushing device, transmission device, and conveying device 1 are provided with a motor I, and a rotary cutter 6 is installed on one side of the motor I; a zigzag cross crushing blade 11 is provided under the roller shaft 4, and a zigzag cross crushing blade 11 is provided below The screw conveyor 7, the roller shaft 4, the zigzag cross crushing blade 11, and the screw conveyor 7 are all located in the casing 3; a drive belt 8 is connected to one side of the motor II, and one end of the drive belt 8 is connected to a screw conveyor 7 The top of the drive belt 8 is connected with a gear 10, and one side of the gear 10 has a zigzag cross crushing blade 11; the crushing device includes two rotating shafts 12, two groups of crushing blades; the transmission device includes a gear 10 meshing mechanism, Drive belt 8.

Described rotary cutter 6 comprises rotary shaft 12, rotary knife rest 14, rectangular blade 15, and rotary knife rest 14 is connected with flat key 13 by rotary shaft 12, is provided with rectangular blade 15 on rotary knife rest 14, and rectangular blade 15 adopts Three rectangular blades with double-sided edges, the rectangular blades 15 are evenly distributed on the circumference.

The two groups of crushing blades adopt crossed zigzag crushing blades 11 .

The transmission device adopts a V-belt transmission mode.

When the banana straw grinder starts to work, firstly, the banana straw 2 is manually placed on the conveyor device 1 of the straw grinder. The distance between the set of rollers is slightly smaller than the diameter of the straw, and the distance between the latter set of rollers is even smaller than that of the previous set of rollers, so as to roll the banana straw. The distance between the first stage rollers is 35cm, and the distance between the second set The distance between the secondary rollers is 32 cm. The radius of the zigzag cross crushing blade 11 is 20cm, and the overlapping distance of the zigzag cross crushing blade 11 is 5cm, so the distance between the two rotating shafts is 35cm. The diameter of the blade near the roller shaft can be appropriately increased to improve cutting efficiency. The main function of the screw conveying device 7 is screw feeding, which pushes the primary crushed straw fragments to the position of the rotary cutter 6 for secondary crushing operation, which can prevent excessive accumulation of straw fragments and stagnation of feeding, so as to improve crushing efficiency. The roller shaft 4 compresses the denser straw longitudinally and absorbs the material, thereby increasing the gap between the layers of the straw, and the layers of the rolled banana straw are separated, which is beneficial to the cutting of the blade. Enter, at this time, the first-level crushing is carried out. After the straw passes through the crushing device, it passes through the separation of each layer, and then is cut into strips with a certain arc, and falls into the next stage of the screw conveying device 7, which sends the primary crushed straw to the secondary rotary In the blade 6, secondary crushing is completed, and finally the crushed stalks are discharged from the discharge port.

The above disclosures are only preferred embodiments of the present utility model, and of course the scope of rights of the present utility model cannot be defined with this. Therefore, the equivalent changes and improvements made by the claims of the utility model still belong to the scope of the utility model. range covered.
